2. In the morning, with the rising of the sun, the garden plants in the green space begin to carry out photosynthesis, absorb carbon dioxide and release oxygen, so the carbon dioxide content in the ambient air gradually decreases, and the carbon dioxide content drops to the lowest point around noon; at night, the plant photosynthesis stops and starts to carry out respiration, but due to the activities of urban people, vehicles, etc All of them release carbon dioxide into the air, and the carbon dioxide in the air begins to rise. So to exercise in the green space, from the fresh degree of the ambient air, it is the best time from 10 a.m. to 2 p.m., but not the best time in the morning.

It's not suitable to take a shower after exercise, especially in summer. After exercise, the whole body is wet. I really want to have the impulse to take a bath. However, in order to keep the body temperature constant after exercise, the blood vessels on the skin surface will expand, the pores will expand, and the perspiration will increase, so as to facilitate the heat dissipation. At this time, if you take a cold bath, the blood vessels will contract immediately and people will easily get sick. If you take a hot bath, you will continue to increase the blood flow in your skin. Too much blood will flow into your muscles and skin, resulting in a lack of blood supply to your heart and brain, which makes you dizzy easily!
